HARTZELL FISHER, OF KANSAS CITY, MISSOURI, ASSIGNOR OF ONE-THIRD TO E.R. MARTIN,'OF KANSAS CITY, MISSOURI.

GRAIN-CAR DOOR.

Specification of Letters Patent.

Patented July 25, 1905.

Application filed April 20, 1905. Serial No. 256,647.

To all whom, it may concern:

Be it known that I, HARTZELL FISHER, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented a new and useful Grain-Car Door, of which the following isa specification.

My invention relates to grain-doors for railroad grain-cars.

Some of the advantages of my grain-door over others are it cannot benailed to the door-jambs. It can be attached to a car at small expense.It can be attached to a car without cutting or disfiguring either of thedoor-j-ambs. With the present makeshift grain-doors the jambs are filledwith nailholes or split and sometimes have to be replaced with newjambs.

The latch-levers with which my door is provided are superior, becausethey are absolutely secure. After they are disengaged the door can beraised by one man without the use of a bar. My latch-levers hold thedoor down as well as against the door opening or jambs.

Referring now to the accompanying drawings, Figure 1 is an outsideelevation of my grain-door, a portion of oneof the jambs being brokenaway. Fig. 2 is an enlarged sectional detail taken on line a Z) ofFig. 1. Fig. 3 is a face View ofone of the concave guides. Fig. 41 is aface view of one of the convex bars which are secured to the door. Fig.5 is an enlarged sectional detail taken on line 0d of Fig. 1.

My grain-door may be constructed of either wood or iron; but it is shownas constructed of wood. In its preferred form it consists of a largelower portion 1 and a smaller upper portion 2, connected thereto byhinges 3. Iron battens 1 and 5 are secured vertically to the twosections of the door, as shown. Secured to the inner side of each jamb 6is a concave metalguide 7. A shim 8 is fitted between one side of theguide 7 and the jamb, as shown in Fig. 2.

Secured to the grain-door in position to engage the guides 7 are twoconvex metal slidebars 9. \Vhen the door is raised or lowered with grainin the car, these bars 9 slide in the grooves of the guides 7 with verylittle friction.

The upper section 2 of the door is provided with two latch-levers 10,pivoted at 12 and 12.

The lower section 1 of the door is provided with two similarlatch-levers 13,.piv0ted at 1 1 and 14.. Each latch-lever 10 or 13 ismade by doubling a fiat iron bar upon itself, forming a loop, handle,and sealing-opening 15. Near the other end the latch-lever is'bifurcated by the separation of the end portions of the bar, thusforming an arm 16, which lies close to the door, and an outstanding arm17. To receive the ends of the inner arms 16, slots 18 are cut in theconvex slide-bars 9. Thus when the end 16 of a latch-bar is thrown intoone of said slots the part 16 is thereby strongly attached to the door.Slots 19 are cut in each guide 7 to receivethe ends 17 of thelatch-levers when they are turned to the position shown in Fig. 1. Asshown in Fig. 5, the slots 19 in the guide-bars? are made wider at oneend, (in this case the lower end.) Thereby when the part17 of thelatch-lever is forced up by pulling down on its opposite end the graindoor will be drawn more and more tightly against the guide-bars 7.

To provide for locking the grain-door in position, two staples 20 areprovided adjacent the handles 15 of the lower pair of latchlevers. Theusual wires are passed throughsaid loops and through the staples andsealed in the usual manner. Thus the latch-levers cannot be turnedwithout cutting the wires. (Not shown.)

It the grain-door be made of iron, the battens 4: and 5 may be dispensedwith and the slide-bars 9 may be integral with the door.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. An inside grain-car door comprising the door proper, convex metalslide-bars secured vertically to the sides thereof, said slide-barshaving slots, a plurality of latch-levers mounted on the door, the outerends of said levers being bifurcated, the bifurcated members nearest thedoor being adapted to enter the slots in the slide-bars, in combinationwith concave guide-bars secured to the door-jambs, said guidebars havingtapered slots, the outer bifurcated members of the latch-levers beingadapted to enter the slots in said guide-bars; substantially asdescribed.

2. An inside grain-car door comprising the door proper, slide-barshaving slots adapted to be engaged by latch-levers, concave guidebarssecured to the door-jambs, said guidebars having slots adapted to beengaged by latch-levers; substantially as described.

3. An inside grain-car door comprising the door proper, slide-barssecured vertically to the sides thereof, said slide-bars having slots; aplurality of latch-levers mounted on the door, the outer ends of saidlevers being bifurcated, the bifurcated members next the door beingadapted to enter the slots in the slidebars; in combination Withguide-bars secured to the door-jambs, said guide-bars having" taperedslots, the outer bifurcated members of the latch-levers being adapted toengage the tapered slots in the guide-bars; substantially as described.

In testimony whereof I afitix my signature in the presence of twoWitnesses.
